Edit past years entries after generating tax report

After generating my 2021 Tax report I am finding that I can no longer edit or add transactions into the year 2021. I found some missing transactions I need to add and a few internal transactions that are marked withdrawals that need changed. I would then like to generate a new report. Is this intended behavior of Accointing.com? What can be done to make it so I can edit 2021? Will I be able to generate a new tax report for 2021 assuming I can edit/add entries in 2021 again?
Thanks
Todd
